What comes after distributed version control?

Question

First there was a centralized model of version control (cvs, svn) and recently a distributed version control model was created (git, bzr, hg). Are there any other types of version control ideologies out there? Or what will be the next new one?

Answer 1

We will be using google wave to edit source collaboratively in real-time.

Answer 2

That's really impossible to say, until someone does it.

Back in the 80's we didn't call our version control systems "centralized", and pine for the days when someone would come up with distributed ones. That's a name people put on them after distributed ones were invented. It is only in retrospect that it looks like an obvious step.
